Furring strip fastening member and construction structure using same

Abstract

A furring strip fastening member comprises a furring strip receiving plate having a through-hole and a female thread section latching section, a rear face plate having a through-hole, a spring section and a female thread section. The spring section connects the furring strip receiving plate and the rear face plate. The female thread section has a through-hole having a thread formed in the inner periphery thereof, and is latched by the female thread section latching sections. In the construction structure for a building, the furring strip fastening member is connected to skeleton wall of building that is formed of concrete wall and a heat insulating material disposed outside the latter, in a state where the female thread section is screwed to the bolt. The furring strip receiving plate presses against the furring strip and the rear face plate presses against the heat insulating material.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates to a furring strip fastening member that is used for fastening a furring strip to a skeleton wall of a building made of concrete, for instance reinforced concrete, pre-cast concrete, lightweight aerated concrete or the like, with a predetermined spacing being provided between the furring strip and the skeleton wall.[0003]2. Description of the Related Art[0004]In conventional techniques, heat insulating materials are installed to the exterior of skeleton walls in buildings made of concrete, an air layer is provided outward of the heat insulating material, and then siding is attached, with the air layer interposed in between. For instance, Japanese Patent Application Laid-open No. 2006-90045 discloses an exterior finishing material fastening fixture comprising a channel that is supported by a bolt to which there is mounted a reinforcing member having a female thread section and a fixing secti...

AI Technical Summary

Benefits of technology

The present invention provides a furring strip fastening member and a construction structure that uses the furring strip fastening member. The furring strip fastening member allows fixing a heat insulating material over long periods of time by way of a simple structure. A female thread section and a spring section connect the furring strip receiving plate and the rear face plate, allowing the furring strip receiving plate to press against the furring strip and the rear face plate, over long periods of time, via the reaction of the spring section. The female thread section is latched by the female thread section latching section, suppressing loosening of the bolt and ensuring firm fixation of the furring strip fastening member. The furring strip receiving plate has a bent flange at the outer edge and the rear face plate is substantially circular, allowing for easy adjustment and installation of the furring strip fastening member.

Problems solved by technology

In order to fix the heat insulating material to a concrete wall in the exterior finishing material fastening fixture set forth in Japanese Patent Application Laid-open No. 2006-90045, however, a separate heat insulating material must be fixed by way of a heat insulating material fixing plate, which is troublesome.

Also, the heat insulating material fixing plate may loosen over time, or on account of earthquakes or the like, whereby fixing of the heat insulating material may become insufficient.
